DigiMon - Digital Monitoring of CO2 storage projects

Results

Whilst a number of demonstration projects have shown the feasibility of CCS, operations need to be cost effective and easily scalable in size and number.

A key component in the operation of any CCS project is measurement, monitoring and verification (MMV), which must demonstrate that projects are planned and executed in a societally acceptable manner and ensure safety and containment of injected CO2. Analogue / digital sensors and single purpose systems are available for CO2 monitoring and detection, providing accurate and comprehensive measurements with a significant range of resolution and uncertainties. This is often at prohibitive costs, and seldom in combined systems.

A key scientific challenge is to deploy a cost-effective optimal combination of technologies that can reduce the uncertainties, collectively improving the probability of successfully verifying containment or detecting breach in CO2 barriers.

The overall objective of the DigiMon project was to “accelerate the implementation of CCS by developing and demonstrating an affordable, flexible, societally embedded and smart Digital Monitoring early-warning system”, for monitoring any CO2 storage reservoir and subsurface barrier system, receiving CO2 from fossil fuel power plants, oil refineries, process plants and other industries

Sub-objectives for the DigiMon project included:

1. Provide a system for monitoring the CO2 plume and identify and provide early-warning of actual or potential breaches in the subsurface barriers.
2. Provide a flexible and interchangeable system with respect to the environment (offshore or onshore) and new system components provided by market-driven technology development.
3. Provide a societally relevant monitoring system that addresses the views and worries of various stakeholder groups and citizens.
4. Provide knowledge communication and dissemination to the public and policy makers.

Physical parameters that are influenced by migration and saturation of CO2 outside the predicted flow path can be measured using a variety of geophysical methods, including acoustic, electro-magnetic (EM) and gravity measurements. The DigiMon concept focused on geophysical monitoring

The DigiMon project assembled a strong international and interdisciplinary consortium with leading research institutions and industry from Norway, the Netherlands, Germany, United Kingdom, USA, Romania and Greece, with professional capabilities and skills from both natural and social sciences.

The innovation of the DigiMon approach lies in the integration of a broad range of technologies for MMV at CO2 storage sites (i.e. distributed fibre-optic sensing technology (DxS), seismic point sensors and gravimetry).

The DigiMon project has involved development and integration of system components that are available at intermediate to high Technology Readiness Levels (TRLs) and raising them to a uniformly high TRL.

DigiMon has also succeeded in bridging technology and social science research, particularly through development of the Societal embeddedness Level (SEL) methodology for evaluating social readiness or maturity of CCS projects.

Workpackages

WP1: Critical technology elements

WP objective: Improved knowledge of accuracy and sensitivity of technologies (DAS, DCS, gravimetry) for monitoring of CO2 storage.

Specific results achieved in WP1 the project include:

• Development of modelling techniques to produce synthetic DAS data and advanced workflows to detect and locate microseismicity recorded on fibre-optic cables.
• Development of DAS data workflows for microseismic monitoring and assessment of ambient noise interferometry methods using DAS.
• Improved TRL and monitoring efficiency of critical DigiMon system components including gravity, seismic and chemical sensing technology.
• The successful completion of fieldwork in Norway, at the Svelvik test site, and Canada, at the Field Research Station (FRS) test site in Alberta.

WP2: Integrating the components

WP objective: Improved understanding of work flows for addressing uncertainties related to integration of multiple data types at various resolution in a common monitoring system.

The work performed has achieved the expected outcome of WP2, more specifically, WP2 has provided the following main results:

• A unified framework for forward modelling the data response of the various system components on a generic CCS site reflecting challenges associated with large-scale CO2 storage offshore

• Further developments of methodology for the integrated interpretation and uncertainty quantification of the system data responses for monitoring large-scale CCS projects
• Inversion framework set up for selected case Smeaheia, including conventional seismic, DAS, 4D gravity, and seafloor deformation data
• Concept report and field trial for cross-well seismic tomography combining conventional and DAS measurements (with different cable designs) using active seismic and ambient noise
• A technical readiness assessment providing

• Identification of critical technology elements (CTEs) for monitoring carbon capture and storage projects.

• Objective scoring of the level of technology maturity for each CTE.
• A report documenting the findings of the assessment.

• Methodology for assessing the separate and joint use of seismicity and induced static strains to calibrate our predictions of geomechanical risks (e.g., induced seismicity) in the context of CCS.
• Recommendations on communication platforms and data standards to facilitate autonomous operations, high-performance computing, and the integration of large data sets
• A demonstration of the Analytical Hierarchy Process (AHP) for optimising the monitoring solution. AHP is a structured and transparent framework for decision-making bringing together technical, economic, and social aspects into a holistic approach for system design

DigiMon Deliverables

The DigiMon project has involved development and integration of system components that are available at intermediate to high Technology Readiness Levels (TRLs) and raising them to a uniformly high TRL.

DigiMon has also succeeded in bridging technology and social science research, particularly through development of the Societal embeddedness Level (SEL) methodology for evaluating social readiness or maturity of CCS projects.
